摘　　要：通过烧结杯烧结过程的解剖分析及运用微型烧结法模拟解剖分析,包钢低硅烧结矿w(SiO2)<5%维持足够机械强度的关键因素是:铁酸钙含量的提高和玻璃质含量的减少。而促成这一成因有3个因素:降低w(SiO2)、提高烧结矿碱度和提高烧结料层。The paper analyses the sinter process at a sinter pot using minor-sinter way.To keep the intensity of the sinter[w(SiO2)<5%] sufficiently is to increase the SFCA and decrease the glass phase.The main measures are to reduce the content of SiO2 in sinter,to increase the basicity of sinter and the height of sintered layer.
